Selectable 1/16 to 32x frequency multiplier. 3.3V operation. Available in 16-Pin (TSSOP or 3x3mm QFN). DESCRIPTIONS The PLL602-35 (PECL with inverted OE), PLL602-37 (CMOS), PLL602-38 (PECL), and PLL602-39 (LVDS) are high performance and low phase noise XO IC chips. They provide phase noise performance as low as - 125dBc at 1kHz offset (at 155MHz), by multiplying the input crystal frequency up to 32x. They accept fundamental parallel resonant mode crystals from 12 to 25MHz.
